To @ZZ whom t Wea/y concern:

Be it known that I, GUsTAv PORST, a citizen ofthe United States ofAmerica, residing at Baltimore city, in the State of Maryland, haveinvented new and useful Improvements in Gas-Regulators, of which thefollowing is a specification,

This invention relates to a governor or controlling device forregulating the iiow of gas between the meter and burners of thegas-service system of a building, the main object in view being toprovide a simple, inexpensive, and reliable construction of device ofthis character whereby the flow of gas admitted will be proportionate tothat consumed and whereby the pressure of the gas in the service-pipemay be reduced to prevent waste in consumption.

A further obj ect is to provide a governing device which may beconveniently applied for use in any house-service pipe and which may beeasily adjusted to compensate for variations of pressure in the mains ofdifferent systems and to correspondingly regulate the amount of gasadmitted to the service-pipe to supply the burner or burners in use.

In the accompanying drawings, Figure 1 is a central vertical section ofa governor embodying my invention, showing the same as arranged for usein a service-pipe. Fig. 2 is a horizontal section of the same, taken online 2 2 of Fig. 1.

Referring' to the drawings, the numerals 1 and 2, respectively,designate sections ofthe gas-service pipe of a building, the section 1leading in practice from a meter and the section 2 forming a conductorfor the passage of the gas to the burners. Interposed between thesesections of' the pipes is the gas controller or regulator constitutingmy invention. This regulator comprises a vertical valve shell or casing3, threaded at its upper end to receive a closing-plug 4 and at itslower end for engagement with an elbow-coupling 5, connecting the samewith the proximate end of the pipe-section 1. A screen 6 of suitableconstruction is disposed at the junction of said pipe-section and elbowto strain the gas and relieve the same of a portion of its impuritiesbefore it passes to the valve-casing.

The casing 3 is of T form and is accordingly provided with. a lateraloutlet 7, connected by a T-coupling 8, and an interposed union 9 with.the proximate end of the pipesection 2, the union 9 connecting theoutlet 7 of the valve-casing with the lateral inlet 10 of the coupling'.A drip pipe or tube 11 hangs pendent from the coupling 8 and is threadedat its upper end for engagement therewith and at its lower end for thereception of a head or cap 12, supporting a petcock or drain-valve 13.The water and other impurities contained in the gas and deposited in thecoupling 8 and section 2 of the servicepipe pass by gravity into thedrip chamber or tube 11 and may be discharged therefrom whenever desiredby opening the valve 13.

Arranged within the valve-casing 3 is a tube or valve-cylinder 14,provided in its side opposite the outlet 7 with a vertical row or seriesor plurality of series of ports 15. The lower end of the tube 14 isthreaded to engage a head 16, having a flange 17 to rest upon the upperend ofthe elbow 5 and which maybe clamped thereagainst by the casing 3or secured in position in any other preferred manner. This head supportsthe valvechamber or tube 14 and is provided with a port 18 and seatadapted to be closed and engaged, respectively, by a vertical movablegas-float or regulating-valve 19, arranged to slide vertically on aguide-rod 20, said rod extending through the chamber 14 and port 18 andbeing supported at its upper and lower ends by bracket-arms 21 and 22,iixed to the valve-chamber and the head.

The valve 19 snugly fits within the chamber 14 and is preferably of thehollow type, being composed of two concave-convex sections suitablyunited and forming a valvebody which is approximately of elliptical formin transverse section. The upper and lower walls or sections of' thebody are formed with openings for the passage of the rod 20, whichopenings are of somewhat greater size or diameter than the rod, so thatthe flow of gas through the valve-chamber will when the valve is seatedbe reduced to the minimum, but not entirely cut oil.

When the gas is turned oii", the valve 19 seats upon the head 16 andprevents the passage ot the gas to and through the ports 15, exceptthrough the small rod-openings in the valve-body. Upon turning on thegas the valve is lifted to a greater or less extent, according to thepressure of the gas, causing it to ascend in the chamber 14 and opencommunication between the pipe-section 1 and one or more of the ports15, thus regulating the supply of gas to the burner in roportion to theamount being consumed and the pres- IIO sure of the gas in the system.In order to adapt the valve to inter ose a resistance to the pressure ofthe gas ehind it, which resistance may vary according to the pressureand the reduction of pressure desired, one or more weights 28 of annularform may rest upon the upper surface of the valve and surround the rod20, so as to be supported thereby. Any number of these weights may beused, so that the operation of the valvethat is to say, its openingmovement-may be controlled according to the pressure of the gas in themain to supply any desired number of cubic feet of gas per hour inaccordance with the capacity of the burners and amount of gas beingconsumed, so as to effectually revent the waste of gas from a too freesup y Jfrom overpressure.

It Wil be seen that the invention provides a simple and eii'ectiveconstruction of' regulator which may be manufactured and installed at acomparatively low cost and without the necessity of modifying thearrangement of the pipes of a house-service system.

Having thus described the invention, what is claimed as new is 1. Agovernor for gas-burners comprising a casing having inlet and outletports, a

valve-chamber within the easing communicating at its lower end with theinlet-port and provided in its side with a plurality ol' portscommunicating with the outlet-port, a guide-rod arranged within saidchamber, and a hollow valve controlling the ports and slidably mountedon the guide-rod, said valve having openings in its walls for thepassage of the rod and of greater size than the rod to form reducedgasiassages.

2. A governor 'or gas-burners comprising a casing having a bottom inletand a side outlet, a ported head disposed below said outlet, avalve-chamber arranged within the easingr and supported by said head andprovided in its side opposite the outlet-passage with a vertical row ofports, a guide-rod extending through the valve-chamber, a hollow valveguided by said rod and controlling the ports, and a weight seated uponthe valve and about the guide-rod.

In testimony whereof I allix my signature in presence of two witnesses.
